SAFETY RAZOR MMdlmmmm E" 54 I. I AINVENT-OR f I aza'mnozz J- v L v T] a V MM W ATTORNEYS Patented Oct. 7,- 1930 UNITED STATES umes E. CONNOLLY, or BALTIMORE, MARYLAND SAFETY RAZOR Application filed August 17, 1929. Serial No. 386,851.

The invention generally relates to razors of the type disclosed in Patent No. 1,651,917, issued to me on Dec. 6, 1927, and in application Serial No. 273,560 filed .by me on April 28, 1928, in which are embodied the customary handle, clamp plate, guard late, blade and blade guard and lather working rollers and regulating devices, and primarily has for its object to provide certain new and use- 1 o ful improvements in the construction and arrangement of said parts rendering the manufacture of the articles simpler and less expensive and greatly facilitating the use of the razors and the cleansing thereof after use.

An object of the invention is to provide a novel, simplified form of lather reapplication regulating means.

Another object of the invention is to provide a guard plate on which the guard and reapplication rollers are so mounted as to enable the use of the plate, either individually or collectively with remaining parts of the razor as a novel massaging implement. Another object of the invention is to provide guard plate roller bearing lugs with steps where overlapped by the blade to enable gull use of the cutting edges from end to en vide a novel hollow, double ended handle greatly facilitating assembly, disassembly and cleansing of the razor and permitting the convenient storage of first aid preparations in the handle when desired.

Other objects willin part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, then be particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which I Figure 1 is a perspective View illustrating the invention mounted on a razor of well known type.

In the drawin s 1 desi nates the razor e0 handle to which t e clamp ead'is attached, said handle being provided with a threaded socket 2 to receive the threaded shank 3 of the clamp head 4. The guide lugs 5 of the clamp head pass through suitable receiving, apertures in the guard plate 6 which is also provided with an aperture to receive the shank 3. Between the guard plate 6 andthe clamp head 4 the usual double edged blade 7 isv clamp'ed in the manner illustrated in Figure 1 of the drawmgs. All 10f the above structure will be recognized as conventional and it is to be understood that while I have disclosed the invention as applied to this particular form of razor the invention is not'so limited in applistructures coming within the scope of the appended claims. 1 In the practical development of the invention the side edges of the guard plate are preferably cut out to provide opposed pairs of mounting lugs 8 which provide trunnion bearings 9 for the guard rollers 10, one thereof being mounted at each side of the guard plate. The cut out portions of the plate 6 are deep enough to provide an appreciable space 11 between each roller 10 and the adjacent plate edge to permit free latherpassage and free rotation of said rollers.

Each guard roller 10"ispreferably provided with a grooved face engaging surface, the grooves being arranged in reversed spirals 12 so as to diverge from. or converge .to a point intermediately of the ends of said roller thus forming centrally disposed Vs 13, see Fi ures 1 and 2.

it will be observed by reference to Figures 7 and 8 that the trunnion lu s 8 are stepped down as at 14 beneath the lade engaging surface of the guard plate to enable the blade to overhang clear of the lugs Thus the shaving edges of the blade are not interrupted at the ends by the lugs andit is therefore possible to employ the extreme corners of the blade in effecting accurate trim-shaving operations which are desirable and in fact necessary around the regions of the ears and temple as well as when trimming a mustache.

' One of the principal objects of my present invention is to simplify the structure disclosed in my application for patent Serial Number 273,560 filed April 28, 1928, and to provide a razor structure capable of being quickly and conveniently assembled and dis assembled for cleaning or the like.

To this end I provide a simple regulator unit or member generally designated 15 and illustrated in detail in Figures 4, 5 and 6. This regulator is of the stationary fixed .adjustment type adapted to be held against the guard plate in a single, fixed operative position assuring proper cooperative relation of the parts withoutdanger of misadjustment due to vibration or shock.

The re ulator member is preferably formed of thin ut strong spring sheet metal and comprises a central cross web or body 16 apertured at 17 to receive the clamp head shank 3, and at 18 to receive the guide lugs 5 of said clamp head. The sides of the regulator beyond the body 16 are bent downwardly-outwardly as at 19 and are cut out as at 20 to make the regulator light and flexible and to provide regulator side bars 21.

The regulator side bars 21 are preferably curved slightly'a's at 22 to conform to the curvature of the rollers and provide concentric lather passing spaces of fixed dimension. These bars are also bowed slightly away from rollers at their central portion as at 23 to tend to localize the lather at that point, and at their extreme corners, they are preferably cornered-in as at 24. to overlie 2.

portion of the roller ends and tend to thwart dripping of later off the roller ends.

The end edges of the regulator are turned as at 25 to provide finger grips which greatly facilitate mounting and removal of the regulator, and to further provide for mounting the regulator. especially upon the guard plate 6, the regulator is provided with notches 26 arranged in the corners provided by the cutouts 20 and adapted to snap over the snap head pins 27 which depend from the concave face of the guard plate. Thus the regulator may be removed bodily with the guard plats. or readily separated therefrom as desire \Vith this type of regulator unit the re application of lather is properly regulated, the lather is well worked and concentrated at the center of the instrument and a construction. is provided which can be quickly and conveniently assembled for use and disassembled for cleansing and storage purposes.

It will be found that the grooved roller equipped guard plate alone may be employed as an efficient skin massaging implement. For this purpose the ends of the plate may be roughened or seated as at 28 to provide finger grips. The rollers being reversely grooved, the combined massage effect is different than a single roller massage because where a single roller will roll back and forth in the same grooves the following roller of a cooperating pair will work the lather or massage cream oppositely of the function of the advance roller so that a vigorous continuously reversing spreading of the-cream or lather is brought about and a real health giving massage assured. See Figure 10.

By reversing the position of the guard plate and eliminating the blade and regulator member as shown in Figure 9, a very eflicient massage implement is provided. The rollersprovide for a sort of anti-friction massage and lather working operation, and between them the smooth clamp head frictionallv engages the face providing a combined friction and anti-friction massage. It will be understood, of course, that the clamp head is narrow enough to fit between the rollers without interfering with their free rotation.

The razor handle is preferably made hollow as at 29 and double ended as shown at 30 in Figure 11 to facilitate assembly and thorough cleansing. Persons who find it necessary to wear eye-glasses for example. having removed them to shave. often find it diflicult to locate the socketed end of the razor handle and consequently lose much time in assembling the razor. In addition to the ease of assembly afforded by the double end sockets, the tubular construction enables the passage of hot water through the handle and thus makes it possible to keep the sockets free from germs and matter upon which germs could feed.

thus always present for immediate use, will assure against infections often resulting from razor cuts.

In Figures 18 and 14 I have disclosed a modified form of regulator member in which the cross web is cut out as at 33 to clear the clamp head screw shank and guide lugs and is provided with end extensions 34 bent to form mounting lugs which may be sprung into recesses 35 provided in the ends of the guard plate and serve as a simple means for holding the regulator member in operative position.

From the foregoing description taken in connection with the accompanying drawings, it is thought that the novel details of construction, the manner of use and the advantages of the invention will be readily apparent to those skilled in the art to which the invention relates.

I claim as my invention:
